Abstract

APARELHO E MÉTODO PARA DETERMINAR FONTES DE SOM VIRTUAIS. A invenção se refere a um modelo de fonte de imagem acústica para reflexões adiantadas em uma sala que é gerado mediante o espelhamento iterativo (305) de salas ao redor de contornos (por exemplo, paredes) de salas da iteração anterior. Os contornos ao redor dos quais o espelhamento é feito em cada iteração são determinados (303) por um critério de seleção específico, incluindo o requisito de que as direções de espelhamento não podem ser invertidas, não podem ser em uma direção excluída e não podem ser repetidas a menos que em uma série contínua de espelhamentos.
